JOSEPH C. HENDERSON, OF ALBANY, NEW YORK, ASSIGNOR TO RATI-IBONE &COMPANY, OF SAME PLACE.

STOVE.

Specification of Letters Patent No. 24,844, dated July 19, 1859.

To all whom it may concern:

Be it known that I, Josnrrr C. HENDERSON, of the city and county ofAlbany and State of New York, have invented, made, and ap plied to usecertain new and useful Improve ments in Cooking-Stoves; and I do herebydeclare that the following is a full, clear, and

exact description of the construction and operation of the same,reference being had to the annexed drawing, making part of thisspecification, wherein Figure 1, is a perspective view of the out sideof a stove fitted with my improvements. Fig. 2, is aperspective viewwith the side plate partially removed to show the parts.

Similar marks of reference denote the same parts.

In the construction of stoves, openings heretofore have been made in theoven, to convey away vapors and fumes from articles that are being bakedin the oven; there have also been other stoves in which a radiating airchamber or space has been provided between the oven and the fire, toprevent too great radiation; other stoves have also been made with doorsat the forward part of the oven to be opened to equalize the heat when aportable oven or reflector is placed in front of the fire for roastingor similar purposes. All these devices however differ essentially frommy said invention which consists in an air chamber so arranged inconnection with the oven and the fire, that a descending draft, thewhole width of the stove, passes between the oven and the fire andenters into the fire to promote combustion. I also make use of anauxiliary heating flue behind the front plate of the stove,

between that and the firebox, which opens into the front part of theoven, so that the draft first becomes highly heated, then passes intothe oven, and thence to the fire, by which a hotdraft is supplied to thefire that greatly promotes a perfect combustion; thence the drafttravels the flues of the stove passing away as usual. By this means I amenabled to bake with a heated current of air in addition to theradiation, ventilate the oven, and make a far more perfect combustion ofthe fuel.

In the drawing a, is the top plate of the desired size and shape, 6, isthe hearth, and c, the oven beneath which the returning flues arearranged in any usual manner, d, is the ring for the pipe, 6, is thefire box and f, is

the door thereof in the side plate 9, of the stove, and h, is the ovendoor. 2', is a hearth and 7a, a damper at the end of the ash box Z.These parts thus far may be of any desired size or shape, in theordinary manner; m, is a division plate forming an air chamber betweenthe fire box and the oven, opening at the top into the oven, and at thebottom into the ash box Z, so that the draft to the fire is taken out ofthe oven, through this chamber, except when the damper 7c, is opened forthe purposes of kindling the fire.

The front plate of the fire box connects with the forward end of theoven, where a damper n, is provided, and openings or a damper 0, areprovided near the top of the front plate.

,0, p, are doors which inclose the front of the stove from a hot airflue; said air coming in contact with the front part of the fire box ishighly heated and passes into and through the oven in the direction ofthe arrow promoting the efficiency of the oven because the entire heatfrom both sides of the fire is taken into the oven, from the one side bythe current of air and from the other by radiation, and a hot blast issupplied to the fire promoting combustion, and then the hot gases makethe circuit of the oven through the flues as usual, heating said oven ina very uniform and efficient manner.

When desired the doors 7;, p, can be thrown open and a roaster orreflector placed in front, which will act to roast or bake by theradiated heat of the front plates; and if the article being baked in theoven 0, will be affected by the vapors from out of this reflector, thedamper a, may be closed and the ash box damper k opened.

It will be seen that by forming a damper in the front end of the ovenplate near the bottom of the oven, and causing the hot air to circulatethrough the same a much better operation is produced by heating thelower and front part of the oven, than in those ovens that are entirelyopen at the front end behind the doors; besides, this damper,whenclosed, keeps in the heat of the oven when a roaster is used in frontofthe radiating plates.

Having thus described the nature and operation of my said invention, Iwish it to be understood that I do not claim a fire pot and ash box overthe oven, neither do I claim an air space between the fire and oven,

of the oven in connection with the descending flue between the frontplate and fire box, whereby the oven can be entirely closed when thestove is in use for roasting as specified.

In witness whereof I have hereunto set my signature this eleventh day ofFebruary JOSEPH G. HENDERSON. Witnesses:
